MySQL的語句的語法

Question

我遇到的問題與這個MySQL的語句：

CREATE TABLE Articoli (Cod_Articolo char(10) NOT NULL, 
Des_Articolo varchar(50) NOT NULL, 
Cat_Articolo char(2) NOT NULL, 
Ubi_Articolo char(6) NOT NULL, 
PRIMARY KEY (Cod_Articolo) 
FOREIGN KEY (Cat_Articolo) REFERENCES Categorie(Cod_Categoria) ON DELETE NO ACTION ON UPDATE NO ACTION 
) ENGINE=InnoDB; 

我得到這個錯誤：

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that 

corresponds to your MySQL server version for the right syntax to use near 'FOREIGN KEY 

(Cat_Articolo) REFERENCES Categorie(Cod_Categoria) ON DELETE NO ACTI' at line 6 

我不明白爲什麼...

謝謝，毛羅

Answer 1

您在這裏缺少逗號：

PRIMARY KEY (Cod_Articolo) 

試試這個：

CREATE TABLE Articoli (Cod_Articolo char(10) NOT NULL, 
Des_Articolo varchar(50) NOT NULL, 
Cat_Articolo char(2) NOT NULL, 
Ubi_Articolo char(6) NOT NULL, 
PRIMARY KEY (Cod_Articolo), 
FOREIGN KEY (Cat_Articolo) REFERENCES Categorie(Cod_Categoria) ON DELETE NO ACTION ON UPDATE NO ACTION 
) ENGINE=InnoDB;
